LIQUID-TREATIENT D.

- Application filed October 14, 1985. Serial lo. 82,390.

My invention relates to a device for supplying liquid to the roots of t-he hair and for heating said liquid before application thereof.

Y It is common practice to employ olive oil in connection with shampoos, and in order to secure desirable results, the oil should be heated' lbefore application. Various expedients have been adopted for this purpose,v 10 all of which are inadequate, andthe apparatus employed has been crude. .In the device of my invention, I have simplified the construction, reduced the cost of manufacture and rendered the device 'capable of produc.

tion at such reasonable cost as to make it available for general use.

The device of m invention is composed of.

constructe parts that' may be easily sim'pl bled and taken apart for inspection or assem repair.

The invention will be more readily understood by reference to the accompanying drawing, in which: y

Fig. 1, is a, longitudinal sectional view through a comb or liquid applying device constructed in accordance wit my invention, and y Fig. 2, is a sectional view on the hne 2-2 of Fig. 1.

The device of my invention comprises a handle, 10, of wood or similar material,hav ing an axial opening for the accommodation of a tube, 11, that extends from end to end of the device. The outer or forward end of the tube is closed by means of a plug, 12, and

within the portion that extends beyond the handle is mounted an electric heating ele-v ment, 13. This element is mounted on a core, 14, and may have an insulating shell, 15, therearound. Wires, 16, are connected to the heating element and extend through the handle portion of'the'tube. lThe tube is reduced in diameter to provide a shoulder, 17, and is threaded at a point adjacent to the shoulder to accommodate a nut, 18, having a flange, 19. The exterior surface of the nut is threaded at a point adjacent to the flange, 19, to receive the interiorly threaded end of the cylinder or tube, 20, which constitutes the hollow head or reseivoir of the comb.

The handle abuts against the nut, 18, at its forward end and at its rear end is held by means of a nut, 21, which engages the exterior of the tube, 10. The forward end of the hollow head, 20, is provided with a removable closure or plug, 22, through which the oil is supplied. A bracket, 23, may be se cured by solder, to the upper outer end of the head, to provide a support for the comb in an inverted position when not in use.

The teeth, 24, of the comb, are provided with longitudinal passages, 25, in communication with the reservoir or space within the hollow head. These passages will, of necessity, be rather minute and no attempt is made herein toillnstrate the process of maiiufacture. In actual construction, vthe passages will be quite large, in diameter, except at the extremities ofthe teeth where the passages will be closed to a very small opening.- I may also find it desirable to construct the teeth of the comb as a separate element rather than as apart of the head, as shown, in which case the teeth will be soldered to the head after the drilling ofthe passages therein. Preferably the teeth and head will be constructed of aluminum in order to assure lightness and a. high coefficient of heat.

transmission. v A i B providing a relatively small reservoir, the eating action will be quick and certain and in view' of the travel of the liquid through the long assage to the point of the teeth, any excess there is no dan r of ssible scalding of the scalp. When e device is not in use, it will be sup rted on the bracket, 23, in an inverted position, and all the liquid in the assages will return to the main reservoir. en it is to be used, the heating coil, will be enered with the device in its inverted position and after a moments heating, it may be reversed in its position and theheated oil will immediately pass downward through the teeth to the point of use. l s

While the use of the device in connection with liquids that are necessarily heated is an important point, it is obvious that the device may be used for applying other liquids to the roots of the hair, such as oils, tonics etc. It will be noted that the construction and assembly of the parts is 'very simple and the device may be taken apart and re-assembled without the use of special tools or exceptional skill. Ohviously, `the device is capable of much modification, and I do notl wish to be limited except as indicated in the appended claims. v

I claim:

1. In a comb of the class described, the combination with a handle, a hollow head,

eat will be radiated and and teeth having passages, of a tube extend.:- ing through the handle and into said hollow head, the end of said tube within the head being closed, and a heating element within and removable through the handle end'or said tube, f 2. In a device of the class described, the combination with a handle, of a tube cX- tending therethrough and projecting beyond the same, a heating element within the projecting portion of said tube,

combination with a handle,of aconib head and apertured comb'teeth ofga, tube extends v heating 1 e a cylinder sui'-, rounding the projecting-portion of said tube.4
